COFFEE-STBAINEB.

Specification of Letters Patent.

Patented Oct. 1,1912.

Application filed April 4, 1918. Serial No. 688,537.

To all whom it may concern:

lie it known that 1, Anna B. Evans, a citizen of the United States;residing at Cheswold, in the county of Kent, State of Delaware, haveinvented certain new and useful Improvements in Coffee-Strainers; and Ido hereby declare the following to be a full, clear. and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to coffee strainers and has for an object toprovide a two iece reticulate or wire mesh ball which is a apted to holdground coflco in a coffee pot, and will be composed of a few number 0simple parts which are assembled without the use of solder in themanufacture or similar fastening agents. the primary end sought by thisinvention being to present a device of the above described characterwhich may be manufacturml more cheaply than ordinary devices of thischaracter.

With the above object in view the invention consists of certain noveldetails of Construction and combination of parts hereinafter fullydescribed and claimed, it being understomi that various modificationsmay be made in the minor details of construction within the scope of theappended claim.

In the accompanying drawing forming part of this specificatmm-Figure 1is a front elevation of the device. Fi 2 is a cross sectional view takenon the line 2-2 Fig. 1. Fig. 8 is a cross sectional view through thedevice taken on the line 8-8 Fig. 2. Fig. 4 is a fragmentary sectionalview showing the manner of fastening the wire mesh e ements to theirrespective imperforate bands.

Referring now to the drawing in which like characters of referencedesignate similar parts, the strainer is shown to com rise tworeticulate members 10 and 11 whic 006 orate in forming a hollow wiremesh all adapted to contain ground miles, the ball being adapted to besubmerged in a coffee pot in the usual manner, and hold the groundcoffee against escape into the liquid.

In constructing the device the member 10 is formed from a hemis hericalwire mesh element 12 the circular e go of which is bent to form anoutwardly openin hook-like flange 13. A cylindrical imper orats metalban 14 is bent at one edge to form an inwardly-openinfiz hook-likeflange 15 adapted to engage the ange of the wire mesh memer pressurethen being applied to press both flanges into binding engagement witheach other and )revent separation of the parts, the parts thus beingsecured to ether without the use of solder or similar fastening means.The free circular edge of the metal band is bent back upon itself toform an outwardly opening hook-like flange it), and at diametrically op)osite points in this flange spaced mrnllcl slits are formed and thematerial ticrcbetween straightened out. to form straight tabs 17,tllcse, tabs being terminally bent inwardly and lmcltwardly uponthemselves to form inwardly opening books 18.

The member 11 is formed from a homispherical wire mesh element It) thecircular edge of which is bent to form an outwardly opening hook-likeflange 20. A metal band 91 is formed on one edge with an inwardlyopening hook-like flange 22 which is pressed into binding engagementwith the. flange 20. The free circular edge of the hand is rolled backupon itself to form an outwardly opening hook-like flange 23. and atdiametrically opposite points in this flange spaced slits are formed andthe material thorchetween straightened out to form straight. tabs 24.

Now suppose that the ground coflce has been placed in the member 11. Themember 10 is now placed upon the member 11 with the hooks thereofengaging the outer faces of the tabs 94 of the member ll. Both membersare now pressed to other and rotated a half turn in o posite directions,the books 18 of the mom or 10 during this operation riding intoengagement with the hook-like flange 10 of the member 11. Both membersare now locked together and form a hollow wire mesh wall for thereception of the ground coffee. To separate the members the aboveoperation is reversed.

What is claimed, is

A cotl'ee strainer com rising reticulate members cooperating in orming ahollow ball, each member comprising a wire mesh element and a bandhaving a rigid interlocking hook connection with said element, thecircular free edges of both bands being rolled back and formingoutwardly opening contacting hook-like flanges, there being parallelslits formed at diametrically opposite. points in the hook-like flangeof one of the bands with the material 5 therebetween tubs adapted toengage the inner surface of straightened out and terminally rolled backthe first-named band. 10 to form hooks adapted to lockmgly enga e Intestimon whereof, I affix my signnture, with the hook-like flan of theother ban in presence 0 two witnesses.
